About us

ERRATUM: In the last issue of weeklyOSM we used an image from this video and stated that it was Newcastle, but it wasn’t. The picture showed the city of Liverpool. It was an oversight from one of our editors who is a fan of Newcastle United. 😉

Mapping

OSM contributor Adam Schneider has mapped features of the recent volcanic eruption in Leilani Estates, Hawaii including fissures and lava flows.

Chris Eshun, a youthmapper from Ghana, made a map of recently flooded areas in Tarkwa using OSM data.

Paul Johnson points out that a more completionist view towards lane tagging to include bicycle lanes may be better than the wiki’s view, which encourages error by omission in complex lane situations. The most common answer he receives is that changing the meaning of a tag that is used millions of times is counterproductive at this point and to propose a new tag, which includes lanes of any kind.

Community

OpenStreetMap Belgium’s ‘Mapper of the month’ features Yasunari Yamashita and Tomoya Muramoto. Yasunari hosts a continuous mapping party in Japan. Tomoya is also active as an editor for the Japanese language team of WeeklyOSM.

sev_osm publishes a Twitter moment about two weeks of OSM and free Geomatics training in N’Djamena (Tchad) targeted to local students, teachers and professionals from both the private and public sectors. The courses were facilitated with the help of members of Chadian community and a Togolese mapper with the support of the International Organization of Francophonie (OIF).

OpenStreetMap Foundation

The minutes of the OSMF’s License Working Group meeting on May 10th is available. The topic was mainly regarding various data protection concerns.

A blog entry in the official OpenStreetMap blog summarizes upcoming changes in connection with the General Data Protection Regulation (GDPR).

An FAQ of the OSM Foundation answers several data protection questions currently asked by many website operators who integrate services of the OSM Foundation (tile.openstreetmap.org, nominatim.openstreetmap.org, api.openstreetmap.org).

The Minutes of the Data Working Group meeting on March 13th is online.

Events

The details about the academic track submission for FOSS4G Europe 2018 are available now.

Maps

Hartmuts MapOSMatic instance has recently served its 20,000th request.
It has also received a database upgrade/reimport to be able to render OpenStreetMap Carto v4.x stylesheets, so the OSM default style is now up to date with the OSM website again.
There’s also now a DokuWiki instance running on the server that provides more detailed usage instructions, descriptions of available stylesheets, and other information related to the print service.

Alex Kemp reports on landrises and landfalls due to termination of mining activities and the effects of stopping the pumping that kept the shafts from flooding on the underground water tables.

switch2OSM

A team at MIT is currently developing a new navigation method that relies less on highly detailed maps and more on sensor technology which also makes use of OpenStreetMap data.

Software

A Java bug in Debian renders JOSM unusable for all users of Ubuntu 18.04 LTS (Long term support). Meanwhile user abienvenu created a Docker container for JOSM so we can get by while waiting for Ubuntu to fix this in an update.

Apple cracking down on applications that send location data to third-parties

MapsMania blogs about Antirubbersheeter, a tool that ease the use of Leaflet with any image, for instance with vintage maps.

Programming

In response to Google’s price increase and not totally satisfied with switch2osm.org‘s tutorial u/Overv created a batteries included Docker image containing a way to follow minute diffs of OSM and render tiles for a given region. As he will use this in production himself, it will be kept up-to-date.

Complying with the GDPR will require changes to OpenStreetMap.org’s registration form for new mappers and requesting explicit agreement of all mappers to the new API’s and website’s terms of use. The technical implementation on how to accomplish this is being discussed on GitHub.

As announced previously planet.openstreetmap.org now redirects HTTP requests arriving on port 80 to port 443 (HTTPS).
